For a boat building or repair job to turn out best, it's important you use high-quality products. WEST SYSTEM® 105 Epoxy Resin and 205 Fast Hardener combine to form an excellent material for making strong structural bonds, applying reinforcing fabrics, and barrier coatings that will stand up to harsh marine environments.
A mixture of five parts 105 Resin to one part 205 Hardener provides a 9-12 minute pot life and 60 to 70 minutes of working time as a thin film. It will wet out and bond with wood, fiberglass, reinforcing fabrics and metals. This epoxy cures to a rigid, high-strength, waterproof solid in six to eight hours at room temperature, and will cure at temperatures as low as 40°F.
The base material of most WEST SYSTEM compounds, 105 Resin is formulated without volatile solvents or odor and has a relatively high flashpoint, making it safer to work with than polyester or vinyl ester resins.
